Hafiz whose beard hasn?t yet began to grow as Imaam

Assalam o alaikum,
Respected Mufti Sahab, can a person who has completed his hifz in quran lead the taraweeh salah as he is just 10 years or below and the beard and not started to grow.

2. Can he who is just 10 years or so and a hafiz, does read quran nicely but the beard has not appeared to grow yet lead the fardh namaz of Esah or Magrib or of any other time salah. And in the same jamat a person has a full sharie beard and reads surahs which he knows but does not read like that of a hafiz, should he lead the jamaat as he has a beard or will the hafiz who reads surahs correctly and nicely but has no beard lead the namaz.

1) No. If he is not Baaligh he cannot.
2) If the Hafidh is not Baaligh then he cannot lead the Fardh or the Taraweeh Salaat. The other person should lead the Salaat who has a beard and knows just a few Surahs, provided he does not make major errors whilst reciting.
